Spock and Nurse Chapel continuity problems.

In contrast to the Original Series, where Nurse Chapel’s attraction to Spock goes unrequited and there is no reason to think they are a good match, in Strange New Worlds she seems like the obviously right choice for him. And he seems to know it.

Also, in TOS there is zero indication they had a previous relationship. This is one of several aspects of SNW that creates continuity problems for the Star Trek universe. But they might be able to retcon it somehow!
